Question

A saturated liquid feed containing 45 mole % chloroform and 55 mole % benzene isfed to a

continuous fractionating column to yield a distillate and residue product with 95 mole %

chloroform and 95 mole % benzene respectively. The VLE datamay be represented by the

following relationship. y = 1.29x + 0.25x2 – 0.54x3

Where,

x, y - Mole fractions of chloroform in the liquid and vapor. Determine
